20. If you do not have complete knowledge about anything, better keep your mouth shut. You might think that speaking about something without full knowledge is trivial matter. But it might have grave consequences

21. When you hear something malicious about someone, keep a favorable view about him/her until you attain full knowledge about the matter. Consider others innocent until they are proven guilty with solid and truthful evidence

22. Ascertain truth of any news, lest you smite someone in ignorance & afterwards repent of what you did

23. Do not follow blindly any information of which you have no direct knowledge. (Using your faculties of perception and conception) you must verify it for yourself. In the Court of your Lord, you will be held accountable for your hearing, sight, and the faculty of reasoning

24. Never think that you have reached the final stage of knowledge and nobody knows more than yourself. Remember! Above everyone endowed with knowledge is another endowed with more knowledge [12/76]. Even the Prophet [p.b.u.h] was asked to keep praying, “O My sustainer! Advance me in knowledge.”

25. Believers are but a single brotherhood. Live like members of one family, brother, sister unto one another
